Before installing the app, please refer to this article to make sure that your system meets the minimum requirements.
TradingView Desktop for Windows is distributed as an app package (file TradingView.appinstaller). Usually, Windows can work with such files right out of the box but sometimes your Windows may not recognize appinstaller files (more often when your system is not up to date). In this case, you will see the "How do you want to open this file?" dialog when running the TradingView app package. As the first thing to do, we always recommend updating your Windows up to the most recent version. If that is not possible, use App Installer for Windows 10 from Microsoft Store to install the TradingView Desktop on your computer.
A few users have reported to us that the app cannot be installed due to an error message that says “App installation failed with the following error message: error 0x80070490: Opening the package from location TradingView.msix failed. (0x80070490).” If you face this, we recommend installing the Windows update of September 14, 2021 (KB5005565) or newer. Learn more about getting this update here.
